A one-dimensional array, often called an array, is like a single row of boxes. Imagine you have a line of storage lockers at a train station. Each locker can hold one item, and you can access any locker directly if you know its number.

In programming terms, each item in a one-dimensional array is accessed using a single index. For example, in JavaScript, you might create and use a one-dimensional array like this:

let fruits = ["apple", "banana", "cherry", "date"];
console.log(fruits[2]); // Outputs: "cherry"

Here, fruits is a one-dimensional array. You can think of it as a single row of fruit names. To access any fruit, you use one number (the index) inside square brackets.
